Claims13
A pressure relief valve, comprising:
- a housing;
- a structure configured to deflect relative to the housing, wherein the structure comprises a tapered portion;
- a seal configured to form a sealing interface between the housing and an interface surface on an interior surface of the tapered portion;
- and
- a conduit, wherein the housing and the structure are mounted to the conduit, wherein the housing, the structure, the seal, and an outer circumferential surface of the conduit define a cavity, and wherein an orifice defined by the conduit fluidly connects an interior of the conduit and the cavity.
